ORANGE AND LEMON JUICE AND PULP EXTRAC'I'OB.

Specification of Letters Patent.

Application filed August 22, 1912. Serial No. 716,459.

Patented May 13, 1913.

To all whom it may concern:

Be it known that I, FRANKLIN S. FISKE, a citizen of the United States,residing at Baltimore, in the State of Maryland, have invented certainnew and useful Improvements in Orange andLemon Juice and PulpExtractors, of which the following is a specification.

This invention relates to a machine having a rotary reamer forexpeditiously removing from such fruit as oranges and lemons, the juiceand pulp without injuring the rind or skin, in order that the latter maybe left in the best condition for the purpose of being grated or reducedto comminuted form, and for other purposes.

To illustrate my invention I have shown in the accompanying drawing oneform of its embodiment "which is at present preferred by me, since thisform has given satisfactory results. It is to be understood however,that such a machine may be difierently arran ed and organized, and theinvention there ore is not limited to the precise construction shown.

Figure 1 is an elevation showing the juice shield in vertical section.Fig. 2 is a front elevation. Fig. 3 is an enlarged view. an axialsection, of the rotary pulp-remover..

The pulp and juice remover comprises a reamer head, A, whose body issolid and is approximately cone-shaped, whose large end is flat at, b,and whose small end or point, a, has. a cup-shaped cavity, d, formed inthe solid head. The cone-shape is not that of a straight taper from thelarge end to the point, but instead is'curvedan axial section view, asin Fig. 3, showing a contour like one end of an ellipse. This reamer hascorrugations, e, that extend longitudinally or parallel with the axis;the corrugations, e, taper and become smaller as they approach the ointend of the cone and the small end oftheraised partof each corrugationterminates at the said cavity, d, and these ends form teeth, f, plainlyseen m Fig.

3; all of these teeth to ether form a circleor annular cutter aroun thecavity and'constitute an important feature of the invention.

The cone-shaped reamer is mounted on a shaft, 9, whose end, It, entersthe center of the cone at its large flat end, I).

The cone-shaft turns in suitable bearings, i, resting on supports, 9';and a driven pulley, It, is mounted on the shaft, while a belt,

Z, on the pulley receives motion from any suitable source causing thecone-shaped reamer to revolve.

A suitable housing or shield, N, is stationar and surrounds and inclosesthe coneshape reamer as shown;v this inclosing shield, in the presentinstance, is attached to one of the supports, 7', but of course it maybe supported by any other means. The shield has at its front a circularopening, in, and at its bottom a discharge spout, o.

The fruit, for instance an orange, that is.

to be operated on by the machine, should first be cut into halves sothat one half will be in readiness to be grasped by one hand of theattendant or operator. When this machine is in motion, the attendant oroperator will grasp a separate one-half of an orange, a lemon, orwhatever the fruit ma be, and with the rounded or convex side 0 the halfpiece contactin with the palm of the hand,

from the rind or skin; the juice and pulp will pass down the dischargespout, 0, and will be received into any suitable vessel which theattendant may place below the spout in the position designated, 2. Theattendant will then lace the empty rind of the half piece of fruit inanother vessel, and proceed to apply another half piece of fruit againstthe point-end of the revolving reamer, as already explained.

The shield, N, that incloses the revolving reamer collects the juice ofthe fruit, and prevents it from being scattered by the action ofrevolution of said reamer.

The rinds of the fruit, by the operation above described, are left ingood condition y to be handled for grating.

Having thus described my invention what I claim and desire to secure byLetters latout is 1. A machine for removing the juice and pulp fromfruit such as oranges and lemons, comprising a head ap 'n'oxiniatelyconcshaped and provided at its small end with a cavity, and havingcorrugations extending parallel with the axis of said head and the smallend of the raised part of each corru- Eation forming a tooth at'saidcavity, wherey an annular-shaped toothed cutter is produced around thecavity. 1

2. In a machine for removing juice and pulp from such fruit as orangesandlemons, the combination of a horizontal revoluble shaft, a solid headwhose exterior is approximately cone-shaped and attached to the shaftand said head provided at its small end with a circular cup-shapedcavity formed in the solid head, and a circle of toothed cutters aroundsaid cavity. 15 In testimony whereof I afiix my signature in presence oftwo witnesses.
